AD2 will likely never get used by me on a project. Although, I did use it to help test the wrappers for the new EZplayer Pro 1.2.0 that's just been released.
I'm after Core improvements like the revised Audio Snap (which I hope has better detection algorithms), stackable FX and Sends in the Console (which I have probably whined about for 4 years), Vocal alignment tool and the Drum Replacer which is in process.
I haven't used X3 in a single project so the core improvements there will be like new toys to me, as well.
EDIT: I forgot to officially mention - Platinum.
